To all witom it may concern:

Be it known that l, ELIAS-J. EMDERY, a citizen of the United States,residing at Portsmouth, in the county of Rockingham and State ofNew'Hampshire, have invented Fit new and useful. Improvements in RubberHeels, of which the following is a specifioation.

This invention relates to rubber heels, and embodies certain new anduseful improvements in the type of heel disclosed in my formerapplication, allowed August 26, 1915 and bearing the Serial Number2,725.

In the construction of the heel covered by my application hereinabovereferred'to,

useis made of reversible plugs constituting the wearing surfaoeflof theheel, and which plugs are individually and detachably associatedtherewith, while my latest improvements embody a wearing surfaceconsisting of plugs adapted to be permanently fired to the body of theheel, and wherein two or more plugs as a unit can be quickly and easilyassociated therewith in a manner to prevent lateral movement of theplugs with relation to the body of the heel.

The nature and advantages of the invention will be better understoodwhen the following description is read in connection with theaccompanying drawing, the invention residing in the construction,combination and arrangement of parts as claimed.

Tn the drawing forming part of this specification like numerals ofreference indicate similar parts throughout the several views and.wherein Figure 1 is a view showing my improved heel fastened to a shoe.Fig. 2 is a top plan view of the heel. Fig. 3 is a sectional viewtherethrough taken on line 33 of Fig. 2.

Fig. 4 is a bottom plan view. Fig. 5 is a sectional view taken on line55 of Fig. 4.

Fig. 6 is an enlarged detail View of a double plug. Fig. 7 is a bottomplan view of the modified form of heel.

Before entering into a detail description of what is herein shown, Idesire to have it understood that do not limit myself to this preciseconstruction, as various changes may be resorted to when desired as fallwithin the scope of the appended claims. Referring more particularly tothe drawing 10 indicates the body portion of the heel, which may beconstructed from any suitable resilient material preferably rubber, andof any desired dimensions. The upper Specification of Letters Patent.

Application filed December 1, 1915. Serial No. 6t,522.

surface of the heel, or that side which is arranged adjacent the upperofthe shoe when the heel is secured to the latter, is cut away toprovide an enlarged recess or pocket 11, the vertical wall 12 of whichis scalloped around two sides and one end in any suitable manner,preferably in a manner to provide segments of a circle such as indicatedat 13. The bottom 14 of the heel is provided with a plurality of.recesses 15, each of which communicates with the pocket 11 by way of arestricted bore 16, to permit the plugs constituting the tread surfaceof the heel to be easily and quickly associated with the body portion 10in the manner to be presently' described. As hereinabove stated theseplugs can be individually associated with the heel 10,- or two or moreplugs as a unit, such as shown in Fig. 6 may be united with the bodyportion 10. A single plug consists of relatively large end portions 17and 18 respectively, which are connected by a reduced shank 19, theplugs being constructed-from any suitable resilient material, preferablyrubber possessing a high degree of resiliency. The plugs are associatedwith the body portion 10 by insertlng the end 17 into the pocket 11 fromthe underside of the heel through the restricted bore 16, the said endbeing of such dimensions as to snugly fit within one of the segments 13,and lie flush with the upper surface of the heel. The lower end 18 ispreferably beveled as at 20, and during the operation of associating theplug with the body portion 10 in the'manner hereina-bove stated, thelower end 18 is partiallyfitted within one of the recesses 15 the wallsof the latter being correspondlngly beveled with respect to the beveledportion 20, which construction together with the manner in which the end17 is connected with the heel, eliminates all lateralrmovement of theplug with respect ,tothe body portion 10. It is of course to beunderstood that the end portions 17 and 18 respectively may be of anycross sectional configuration, to accommodate themselves to theparticular formation of the recesses in the heel 10 which receive thesame. However as shown in Fig. 6 ll propose to manufacture two or moreplugs as a unit, in which instance the attaching end portions 21 of therespective plugs are connected by means of reduced shanks 22 to a singletread portion 23. The ends 21 are adapted to be inserted within thepocket 11 from the under side of the heel in the same manner hereinabovedescribed in connection with a single plug, and snugly fitted within theproper segments 13 formed in the wall 12 as shown, while the treadportion 23 is adapted to be received within -a suitable recess formed inthe bottom of the body portion 10. The tread portion 23 is preferablybeveled as at.24, as is also the wall of the recess in which the treadportion 23 is partially fitted.

Obviously a single heel may be provided with a' number of single plugsand also a plug constructed in the manner shown in Fig. 6, that is tosay a single tread having two or more plugs integrally connected in themanufacture of the article. Subsequent to the insertion of the plugswithin the body portion 10, the heel in its entirety may. be secured tothe shoe in any suitable manner, such as for instance by means of thefastening elements 25. It is of course to be understood that the duplexplug such as disclosed in Fig. 6 can be detached when worn and a new oneinserted in lieu thereof. The plugs provide a plurality of independentgripping surfaces for the ground, and collectively produce a' non-slipheel. The combined elasticity of both the-heel 10 and the plug producesa heel of the-character disclosed which possesses a high degree ofresiliency and maximum efiiciency.

It is believed that from the foregoing description the nature andadvantages of the invention will be apparent without requiring a moreextended explanation, it being understood that any number of plugs maybe employed as found necessary or desirable.

What is claimed is e '1. As a new article of manufacture, a heelcomprising a body having a recess on one side, and aplurality ofundercut recesses on the opposite side, said recesses being comthe plugand head respectively and arranged in one of said openings.

2. As a new article of manufacture, a heel comprising a body having arecess on one side, and a plurality of undercut recesses on the oppositeside, the walls of said recesses being beveled, said recesses beingcommunicative by openings through the body of the heel, one of saidrecesses communicating with more than one of the openings, a plug fittedin one of said undercut recesses on one side of the heel and including ahead fitted in said recess on the opposite side of the heel, and havinga portion spaced from the walls thereof to permit of its expansionwithin said recess, and anintegral stem connecting the plug and headrespectively and arranged in one of said openings.

p 3. As a new article of manufacture, a heel comprising a body having arecess on one side, and-a plurality of undercut recesses on the oppositeside, said recesses being communicative by openings through the body ofthe heel, one of said recesses communicating with more than one of theopenings, the wall of the first mentioned recess being formed withspaced depressions, a plug fitted in one of said undercut recesses onone side of the heel and including a head arranged in the recess on theopposite side of the heel and fitted in one of said depressions, and anintegral stem connecting the plug and head respectively and arranged onone of said openings.

In testimony whereof I aflix my signature in presence of two witnesses.
